DTC CHECK/CLEAR
1. CHECK DTC WITH INTELLIGENT TESTER II
DTCs which are stored in the ECM can be displayed with the
Intelligent Tester II and generic OBD scantool.
These scan tools can display pending DTCs and current DTCs.
Some DTC aren’t stored if the ECM doesn’t detect a malfunc-
tion during consecutive driving. However, the detected mal-
function during once driving is stored as pending DTC.
(a) Connect the Intelligent Tester II to the Data Link Connec-
tor 3 (DLC3).
(b) Turn the ignition switch ON.
(c) Enter the following menus: Enter/ Power train/ Engine and ECT/ DTC/ Current (or Pending).
(d) Confirm the DTCs and freeze frame data and then write
them down.
(e) See page 05–245 to confirm the details of the DTCs.
NOTICE:
When simulating a symptom with the scan tool to check the
DTCs, use normal mode. For codes on DIAGNOSTIC
TROUBLE CODE CHART subject to ”2–trip detection log-
ic”, perform the following actions.
Turn the ignition switch OFF after the symptom is simulated
once. Then repeat the simulation process again. When the
problem has been simulated twice, the MIL illuminates and the
DTCs are recorded in the ECM.
2. CLEAR DTC WITH INTELLIGENT TESTER II
(a) Connect the Intelligent Tester II to the DLC3.
(b) Turn the ignition switch ON.
(c) Enter the following menus: Enter/ Power train/ Engine and ECT/ DTC/ Clear.
3. CLEAR DTC WITHOUT INTELLIGENT TESTER II
Disconnecting the battery terminal or remove the EFI and
ETCS fuses from the engine room R/B for 60 seconds or more.
But if you disconnect the battery terminal, you should do the
”INITIALIZE” procedure.
